To aZZ whom it may concern: tional view taken centrally through the share Be it known that I, FRANKLIN H. NICHOLS, and the forward end of the moldboard.

Fig. 7 is a detail longitudinal seccured thereto by means of suitable fastenings 100 11-. It will be understood that the share fits upon the recessed or cut-away portion of the moldboard, and its rear end abuts firmly against the opposite shoulders 12, formed by the recessed portion of the moldboard and at opposite sides of the tongue 7. The point of the share. is enlarged, so as to form a shoulder 13 upon its under side and abutting firmly against the forward end of the shoulder 9 on the moldboard.

As hereinbefore set forth, it is designed to adjust the mold board and share from one side to the other of the plow-beam, and to provide for this movement the moldboard is pivoted to the forward end of the landside by means of a forwardly-projecting pivot-pin 14., provided upon the landside and pivotally received within a socket 15, formed in the rear side of the shoulder 9 at the forward end of the moldboard. The rear end of the moldboard is pivotally connected to the rear end of the landside by means of an arm L, which is provided at its outer end with divergent members 16, secured to the inner or rear side of the moldboard. The oppositeend of this arm is provided with a pivot-pin 17, received within a socket 18, formed in the rear end of the landside.

From the foregoing description it will be apparent that the moldboard is pivoted to the opposite ends of the landside, so as to swing laterally beneath the latter and to opposite sides thereof, as indicated by the full and dotted lines in Fig. 3 of the drawings. The arm L is braced by means of a rod 20, having one end connected to an intermediate portion of the arm and its opposite end secured to the under side of the moldboard near the for ward end thereof.

To look the moldboard in either of its adj usted positions, there is provided means comprising a substantially L-shaped arm 21, extending rearwardly from the arched portion of the beam, the rear angled end of this arm being located approximately over the rear end of the landside and extending downwardly. Pivoted to the rear end of the arm 21 is a sheath 22, which is provided at its inner end with an offset perforated ear 23, which forms the pivotal connection with the supportingarm 21. Upon the inner side of the sheath and extending longitudinally of each edge thereof is a flange 24, and slidably received between the opposite flanges is an arm 25. Secured to thepivoted arm L is a bracket M, which is designed to pivot-ally support a pivot-pin P, projecting from the outer end of the slidable arm 25. It will be understood that the pivotpin P projects at the front side of the slide, so as to be received between the flanges 24 during the movement of the slide. Alongitudinal slot 26 is formed in the sheath, and the opposite longitudinal edges of the slot are provided with rearwardly-extending flanges 27.

Mounted within this slot and pivoted intermediate of its ends to the opposite flanges 27, as indicated at 28, is a latch E, having its outer free end provided with a catch-head 29, extending forwardly through the slot 26 and designed to engage against the outer end of the slide 25. Interposed between the opposite end or thumb portion of the latch and the sheath is a coiled spring 30, normally holding the catch-head 29 within the slot in the sheath.

The moldboard being at either side of the plow-beam and it being desired to adjust the same to the opposite side of the beam, the latch E is operated to disengage the catchhead 29 from the outer end of the slide 25, whereby the moldboard is free to be swung laterally to the opposite side of the beam and upon its pivotal axis. This movement is permitted by reason of the sheath being pivotally connected to the supporting-arm 21 and the slide 25 having a pivotal connection with the moldboard, so that said members may swing laterally with the moldboard and the slide may move longitudinally of the sheath.

The plow-handles 31 are of common or ordinary form, having their forward ends embracing the arched portion of the beam and secured thereto in any preferred manner. The handles also embrace the horizontal portion of the arm 21 and are secured to the latter by means of a substantially U-shaped clamp 32.

Mounted at the forward end of the plowbeam, is a clevis 11, having the upper and lower rearwardly-extending arms 33 and 34, respectively, which loosely embrace the plowbeam and are pivoted thereto by means of a suitable pivot-pin T. The upper arm 33 extends a suitable distance in rear of the pivotpin and each opposite side is provided with an ear 35. It will thus be apparent that the clevis has a lateral movement upon the pivotpin P, and to conveniently adjust the clevis there is provided an operating-lever Gr, having its forward end pivoted to the pin P and snugly embraced by the ears 35. The rear end of this lever extends to a point adjacent to the rear ends of the plow-handles, so as to bein convenient reach of the operator. Located between the plow-handles and secured to the inner sides thereof is a transverse rack N, having the teeth located upon its upper edge and with which the rear end of the 19* ver G adjustably engages. By moving the rear end of the lever G in either direction the clevis is adjusted laterally in an opposite direction, so as to change the direction of the draft. It is preferable to provide the oppo site edges of the lever with suitable notches for engagement with the teeth of the rack, so as to prevent accidental displacement of the rear end of the lever.

Pendent from each side and at the forward end of the plow-beam is a standard K, which is adjustable vertically upon the beam by means of a clamp-plate S, which embraces the standard and is provided at opposite ends with suitable fastenings entering the plowbeam. The purpose of these standards is to support a suitable wheel or roller for traveling in advance of the plow and supporting the forward end of the plow-beam.
